ABSTRACT:
In a case where an AC power is supplied from an AC power source to an AC circuit unit, the AC circuit unit and an DC circuit are connected to each other, a DC power is supplied from the AC circuit unit to the DC circuit unit, the DC power is converted to a required working voltage, and on the other hand, in a case where a DC power is supplied from a DC power source to the DC circuit unit, the DC power is converted to a required working voltage, and the DC power obtained as described above is used as a charging power for charging the secondary battery.
